Very old recipe which was quite popular in my home country but somehow was forgotten , although still made at home , some of homes. Here in New Zealand it is common as is quince jelly , although amounts of fresh fruit are limited.As it requires long time to be cooked , I made it in a slow cooker. So i had to stir only every 30 minutes , instead of constantly.You can also add walnuts, which I did not have when making this paste. It is very yummy and mostly eaten with cheese and crackers on plate.Ingredients
